SWAGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 483,091, datedSeptember 20, 1892.

Application filed February 29, 1892- Serial No. 423,305- (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES H. YARINGTON, a citizen of the UnitedStates, residing at Torrington, in the county of Litchfield and State ofConnecticut, have invented certain newand useful Improvements inSwaging-Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its object to produce a simple, inexpensive, anddurable machine for swaging and reducing wire rods, bars, 850., and forpointing needle-blanks and similar uses, the machine being equallyadapted to swage round and angular rods and bars.

With these ends in View I have devised the simple and novel machine ofwhich the following description, in connection with the accompanyingdrawings, is a specification, numbers being used to designate theseveral parts.

Figure l is an elevation of the machine complete; Fig. 2, a verticalsection on the line w 00 in Fig. 3; Fig. 3, a front elevation; Fig. 4, asimilar view with the face-plate removed; Fig. 5, a section on the liney yin Fig. 1,1ooking toward the left; Fig. 6, a section on the line 2 cin Fig. 1, looking toward the left; and Fig. 7 is a view of one of therollers detached.

1 denotes a standard in which a sleeve 2, having at its inner end a disk3, is journaled. WVithin the sleeve and adapted to turn freely thereinis a mandrel 4, having an opening 5 through it.

6 denotes a belt-pulley keyed to the sleeve, and 7 a belt pulley keyedto the mandrel. Near the forward end of the mandrel is a pair of ears 8,in which arms 9 are pivoted. The rear ends of these arms are outwardlycurved, as shown, and are provided with sockets 10, adapted to receiverollers 11. These sockets arecircular in form and comprise more thanhalf a circle, so that the rollers are held against dropping out in useby meansof the overhanging portions of metal 10 of the sockets. Therollers are held in place against lateral displacement by plates 12,secured to the ends of the arms. Disk 3 is provided with similar sockets10 in its periphery,which also receive rollers 11, said rollers beingheld against being thrown out by centrifugal force by means ofoverhanging portions of metal 10, the same as the rollers in the arms,and being held against lateral displacement by means of a circular plate13, which is screwed to the face of the disk. Between the sockets in theperiphery of the disk are depressions 14, which receive the rollers onthe arms in use, as will be more fully explained. The rear ends of thearms are drawn toward each other, so as to keep the rollers at theirends in contact with the disk by means of a spring or springs 15. In thedrawings I have shown two springs, the ends of which are connected topins 16 upon the arms.

17 denotes the die-case, in the inner face of which is a circularopening 18, through which the mandrel and arms extend into the case. Atthe end of the mandrel within the diecase is a disk 19, having slots 20,through which the arms pass freely and to which the die-plate 21 issecured by screws 22. The die-plate is provided with a slot 23, whichreceives the forward ends of the arms and also the dies 24, which liebetween the arms, as clearly shown.

25 denotes adjusting-screws in the ends of the arms which bear againstthe backs of the 1 dies. These screws are turned in or out in adjusting,as may be required, depending upon the size of the rod that is betweenthe dies, the screws'being of course turned in far of the opening inthedies isbeveled, as shown in Fig. 4, to permit the rod to be convenientlyinserted between them.

29 denotes a pin adapted to pass through a hole 30 in disk 3 and into acorresponding. hole 31 in standard 1, as in Fig. 2, in order to lock thedisk against rotation, for a purpose presently beexpl-a-ined, or to passthrough a hole 32 in the periphery of die-case 17 and into acorresponding hole 33 in die-plate 21, as in Fig. 1, to lock thedie-case against revolution for another purpose presently to beexplained.

The operation isasfollowsz Supposejthat a round rodis to be swaged. Pin29 is passed through hole 30 in disk 3 and into the standard, as in Fig.2, so as to lock the sleeve and disk against rotation. The belt (notshown) is placed upon belt-pulley 7, so that motion is communicated tothe mandrel,arms, dieplate, dies, &c., all of which revolve together.Springs 15 act to draw the rear ends of the arms against the rollers indisk 3, and as they pass the rollers into depressions 14 between themthereby producing a constant succession of blows upon the dies which arerotated constantly about the rod. Should it be required to swage anangular or polygonal rod or bar, pin 29 is removed from hole 30in disk 3andis passed through hole 32 in the periphery of the die-case and intothe dieplate, as in Figs. 1 and 4, thereby locking the die-plate againstrotation, but leaving the sleeve and disk 3 free to rotate as soonas thebelt (not shown) is placed upon pulley 6. It will be understood that themandrel, arms, die-plate, dies, &c., are now held against rotation, butthat the sleeve and disk are free to rotate. The principle of operationis precisely the same as before, except that the blows of the arms uponthe dies are delivered in the same plane instead of in aconstantly-changing plane, as in the other form.

Having thus described my invention, I claim- 1. The combination, withthe sleeve having a disk 3 at its outer end and rollers in the peripherythereof, of a mandrel journaled in said sleeve and having pivotedthereto arms having rollers at their rear ends adapted to engage therollers in the disk, means for imparting rotation to said sleeve andsaid mandrel independently of each other, a die-plate at the forward endof the mandrel, dies in said plate the backs of which are adapted to beengaged by the forward ends of the arms, a suitable case inclosin g thedie-plate and the forward ends of the arms, a spring for holdingtherollers in the arms in contact with the rollers in the disk, and meansfor locking said disk and said die-plate against rotation, so that thesuccessive blows of the dies may be delivered in the same plane or in aconstantly-changing plane.

2. The combination, with the mandrel,dieplate, and dies, of arms 9,pivoted to the mandrel, the forward ends of said arms being adapted toengage the backs of the dies and their rear ends being provided withrollers, a disk between the rear ends of said arms, provided withperipheral rollers and depressions between said rollers, means forrevolubly supporting said mandreland disk, and a spring adapted to'ihold the rear ends of the arms in contact with the disk.

3. The combination, with the mandrel and dies, of arms 9, pivoted to themandrel and adapted to actuate the dies, disk 3 between the rear ends ofsaid arms, said arms and said disk being provided with socketscomprising more than ahalf-circle, rollers in saidsockets, plates forretaining said rollers against lateral displacement, and means forrevolubly supporting said mandrel and disk.

- 4. The combination, with the mandrel, the

armspivoted thereto, disk 3 between the rear ends of said arms andhaving peripheral projections, and the spring acting to press the armsagainst the disk, of the die-plate and the dies adapted to be actuatedby said arms, a case therefor having an opening to receive the mandreland arms, and means for revolubly supporting said mandrel and disk.

drel, die-plate, and dies, of arms 9, pivoted to the mandrel and havingscrews at their forward ends the points of which are adapted 'to engagethe dies and the rear ends of which are provided with rollers adapted toengage other rollers upon the disk, aspring forholding said arms, andsaid disk in engagement, and means for revolubly supporting said mandreland disk.
